VALVE WITH DIAMETER-REDUCED JOINT PART, JOINT FOR DIAMETER REDUCTION, AND PIPE SYSTEM USING THESE VALVE AND JOINT

WIPO Patent Application WO/2007/013654

A1

A valve easily and securely connectable to a pipe merely by tightening the housing thereof for diameter reduction without processing the connected portion of the valve, capable of absorbing vibration with a proper flexibility against the pipe joined thereto, and having excellent durability. The valve comprises a diameter-reduced joint part enabling the joining of pipes for each side independently of each other, capable of always maintaining the high sealability of the valve even when the valve is joined to and removed from the pipe, and manufacturable at advantageous cost. A sealing sleeve (3) formed of a rubber is stored in the diameter-reducible housing (2), and a valve mechanism (4) having a valve element (11) is built in the housing (2) so that flow passages in the housing (2) can be opened and closed and a flow can be controlled. The diameter-reduced joint part (18) reduces the diameter of the housing (2) to sealingly join the joining end part of the pipe (P) for joining with a sealing sleeve (3).
